Functions Of Triglycerides

Question 1

Property: Triglycerides have a high ratio of energy-storing carbon-hydrogen bonds to carbon atoms

Answer 1

• Triglycerides have a high ratio of energy-storing carbon-hydrogen bonds to carbon atoms
• Therefore an excellent source of energy

Question 2

Property: have a low mass to energy ratio

Answer 2

• have a low mass to energy ratio
• making them a good storage molecule because much energy can be stored in a small volume

Question 3

Property: are large, non-polar molecules that are insoluble in water

Answer 3

• is insoluble in water
• water potential is not affected
  i.e. no osmotic effect

Question 4

Property: have a high ratio of hydrogen to oxygen atoms

Answer 4

• have a high ratio of hydrogen to oxygen atoms
• they release water when oxidised
• therefore provide an important source of water, especially for organisms living in dry deserts
